if the run is based off of time spent in the game and not total score, then surely i can just afk on a platform forever? if it IS based off of total score then my bad, but I saw some runs weren't ranked right near around like 6th or 7th or sum

High score category is based off of high score.

To be specific, each minute is 60,000 points, each second is 1,000 points, and each millisecond is 1 point. So a score of 20 minutes is really 1,200,000 points.
